i had seen them for the first time a couple of weeks ago when i went to to get some info for someone. looks promising for those who want an option inbetween the 32/36 & the 38.
the 32/36 progressive are more reliable/adjustable than the stock carbs + as with any of these carbs they do away with all the vac lines. it gets more power with same if not better fuel economy (because of one barrel opening first, then the other opening after more throttle is applied) than the stocker. they are good for stock motor applications to ones with a bolt on mod (i.e. header)
with the 34 progressive, it has the same size barrels allowing more air/fuel flow to the engine than what the 32/36 would, but still only one barrel is open at first then the other. they would be good for someone that is doing a little more than bolting on a header to the motor (full exhaust, engine internal mods[to an extent] ignition upgrade, cooling system upgrade)
with the 38 sync. both barrels open at the same time which will allow for quicker initial throttle response, and can provide more air/fuel for highly modified engines with all of the afore mentioned upgrades.
all are better than the stock application, and it really depends what your looking for as to which would be best suited to your application. if your concerned with fuel economy the 32/36 is the way to go.
if your looking to replace the stock one and have future plans of slightly modifying the engine the new 34 would be the way to go as the adjustability would be there where as with the 32/36 you could be limited
as to how highly you could modify your engine with out restricting your performance.
if your going for all out performance the 38 is your best bet.
these are just a few points of interest that may help out.....
